Description

Application

Cholesteryl arachidoante was oxidized and used to study the biological effects.

Biochem/physiol Actions

Cholesteryl arachidonate is a cholesterol ester found associated with the neutral core of low density lipoprotein. Receptor-LDL complexes are taken up by lysosomes and hydrolyzed to release cholesterol from the esters. The enzyme acid cholesteryl ester hydrolase is responsible for the hydrolysis of cholesteryl esters; a defective enzyme can result in the formation of atherosclerotic lesions in humans.

Preparation Note

Cholesteryl arachidonate is a clear, colorless viscous liquid in chloroform.
